Answer:
Gene splicing is a post-transcriptional modification in which a single gene can code for multiple proteins. Gene Splicing is done in eukaryotes, prior to mRNA translation, by the differential inclusion or exclusion of regions of pre-mRNA. Gene splicing is an important source of protein diversity.
Answer:
Explanation:
Species: a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding.
Population: a particular group or type of people or animals living in a place.
Gene pool: the stock of different genes in an interbreeding population.
Mutations: the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes.
Lateral Gene Transfer: the movement of genetic material between unicellular and/or multicellular organisms other than by the transmission of DNA from parent to offspring (reproduction).
Single-gene Traits: when a trait is linked to one gene-pair that consists of two alleles.
Polygenic Traits: is one whose phenotype is influenced by more than one gene.
heir function is to base pair with the codon on a strand of mRNA during translation. This action ensures that the correct amino acid will be added to the growing polypeptide chain. A tRNA molecule will enter the ribosome bound to an amino acid.
Answer:
It isn't safe at all...
Explanation:
Even if remains at constant temperature, while ascending to the surface of the lake Jacques lung pressure will increase if he hold its breath. Thats because the pressure of water weakens and the pre-hold breath in lungs will expand as he rises. This can cause serious lung damage and drowning is possible.
The plant contains vascular tissue and has an alternation of generation. But, it lacks seeds. So, the plant is a Pteridophyte.
- Vascular tissues are absent in thallophytes and bryophytes. They are found in pteridophytes, gymnosperms and angiosperms.
- The sporophyte and gametophyte generation is common in bryophytes and pteridophytes.
- Seeds are produced in plants that come under the group gymnosperms and angiosperms. The presence of seeds is the main characteristic of these groups.
- Thallophytes, bryophytes and pteridophytes lack seeds. The reproduction in plants that comes under these groups occurs with the help of spores.
Thus, the recently discovered species of the plant should be classified based on the presence of vascular tissues, gametophytes and sporophytes. As pteridophytes contain vascular tissues, sporophytes and gametophytes and lack seeds, the plant is a pteridophyte
